  1. Find the Symptoms of a Bad Fuel Pressure Regulator

  2. It is important that a vehicle has a properly working fuel pressure regulator to keep it moving steadily and consistently.

  3. When the regulator malfunctions in some way, it would disrupt the entire internal combustion process which the engine depends on to generate moving power for the vehicle.

  4. There is possibility of a number of easily noticeable symptoms that arises when your fuel pressure regulator goes bad or starts to go bad.

  5. Below are mentioned some of the symptoms that your car show because of a bad fuel pressure regulator. • Engine Misfires • Spark Plugs Covered in Soot • Black Smoke • Tailpipe is Dripping Gasoline • Vacuum Hose Has Gasoline • Engine Won’t Turn Over

  6. Engine Misfires

  7. The most obvious symptom of a bad fuel pressure regulator is an engine misfire and loss of acceleration power.

  8. While driving, suddenly your vehicle will stumble and slow down, then it may go back to accelerating normally for a short time before losing acceleration power again.

  9. Spark Plugs Covered in Soot

  10. If you suspect that you have a bad fuel pressure regulator, take out your spark plug and see if there is any black soot on the end of it.

  11. This soot is the result of oil burning in the engine’s head and you will need to replace both the fuel pressure regulator and the spark plugs in this case.

  12. Black Smoke

  13. You should only be seeing gray or white smoke coming out of your tailpipe and if you start seeing black smoke, the cause can likely be attributed to a bad fuel pressure regulator.

  14. Although there are lots of other reasons why black smoke may be there, it is likely the regulator’s fault if you notice any of the other symptoms listed here too.

  15. Tailpipe is Dripping Gasoline

  16. If your tailpipe is dripping gasoline out of it, then your fuel pressure regulator is probably letting it happen because it has gone bad.

  17. A malfunctioning regulator will allow gasoline to get into the vehicle’s exhaust system and it finds its way out of the tailpipe along with the exhaust fumes.

  18. Vacuum Hose Has Gasoline

  19. One sure way to find out whether you have a bad fuel pressure regulator is to disconnect your vacuum hose from your fuel pressure regulator and see if it has gasoline inside of it.

  20. Be sure to do this while your engine is turned off and if there is gasoline in your vacuum hose, then you have a bad fuel pressure regulator.

  21. Engine Won’t Turn Over

  22. If you try to start your vehicle and it won’t start because the engine doesn’t turn over, then something is wrong with your fuel pressure.

  23. Since the regulator is what manages the fuel pressure, then your fuel pressure regulator is to blame and must be replaced.
